Answer:
200 cm (or 2 meters) or 80% of the original 250 cm is left. let me know if you have any questions.
Step-by-step explanation:
I'm not sure if that's asking for an exact amount or percent, so I will do both.
The trick either way is to match units. we have meters and centimeters. You could make either one match the other. so 2.5 m is 250 cm and 50 cm is .5 m.
You do have to know how many centimeters is in a meter, but once you know that you can set up unit conversions, which are super simple.
there are 100 cm in a m. a unit conversion is basically a fraction that cancels out units. starting with 2.5 m we want to cancel out m so the fraction we use has the m part in the denominator. so 2.5m * (100 cm)/(1 m). (100 cm)/(1 m) is the unit conversion, and just like variables the m in the denominator cancles out the m in the starting value so it turns into 2.5 * 100 cm/1 = 250 cm.
similarly to go from 50 cm to meters you make the unit conversion have cm in the denominator. so 50 cm * (1 m)/(100 cm) = .5 m. again, the cm int he denominator cancels out the cm in the unit being multiplied. Let me knwo if this is still not clear.
Anyway, now we have the numbers we need. let's make them all cm, I think using the smallest unit is usually easiest. so that's 250 cm total and 50 cm used.
In pure numbers, that means 200 cm is left (which is 2 meters) after 50 cm gets used.
percents is a little trickier. if 250 is 100% then 50 is 20%, which you can get by doing 50/250. if you do not know, a fraction a/b gives you the percent a is of b. Or rather it gives you a decimal, and if you multiply it by 100 it gives you the percent.
anyway, if 20% is used then 80% is left. if you did 200/250 you would get that.
(2x + 4) + (-7 - 3b) + (5 - 8x)
)
Please help
Answer:
Step-by-step explanation:
First, open the brackets.
(2x + 4) + (-7 - 3b) + (5 - 8x)
= 2x + 4 -7 - 3b + 5 -8x
Simplify the like terms.
= 2x - 8x - 3b + 4 -7 + 5
= -6x - 3b + 2

(PLEASE HELP) What is the value of x?
Enter your answer in the box.
x =
Answer:
x = 12
Step-by-step explanation:
(10x - 20)° + (6x + 8)°= 180°
(Linear pair angles)
(10x - 20 + 6x + 8)°= 180°
(16x - 12)°= 180°
16x - 12 = 180
16x = 180 + 12
16x = 192
x = 192/16
x = 12
Answer:
so x would equal 12
Step-by-step explanation:
(10x - 20)° + (6x + 8)°= 180°
so you are going to want to combine like terms which would be
10x and 6x, and 20,8
10x+6x=16x
20-8=12
16x-12=180
now you want to get 12 on the opposite side of the equal side so you add (since it is negative) 12 to each side
which gets rid of the first 12
16x=180+12
now you can add 180+12
and you get 192
so now we want to get x by itself in order to do that you must divide
you are going to divide by 16 an each side and the 16 cancels out the first 16
16x/16=192/16
x=192/16
and 192 divided by 16 is 12
so you answer is
x=12
Hope this made sense :)

Answer:
1725ft^2
Step-by-step explanation:
Area of trapezoid:
[tex]\frac{b_1+b_2}{2}*h[/tex]
Substitute the values and solve:
[tex]\frac{50+65}{2}*30=1725[/tex]ft^2
Answer:
1725 sq.ft
Step-by-step explanation:
Given
Parallel sides of the trapeziod yard = 50ft , 65ft
Height of the trapezoid = 30ft
Therefore, area of the trapezoid yard
[tex] = \frac{b1 + b2}{2} \times h[/tex]
[tex] = \frac{50ft + 65ft}{2} \times 30ft[/tex]
[tex] = \frac{115ft}{2} \times 30ft[/tex]
= 57.5 ft × 30 ft
[tex] = 1725 {ft}^{2} (ans)[/tex]

140°
A
с
O 46°
O 489
O 70°
O 920
Answer:
92°
Step-by-step explanation:
∠C=180-140=40
∠A+∠B+∠C=180
40+2X+X+2=180
X=46
∠B=46*2=92°
Answer: 92 degrees
Step-by-step explanation:
The exterior angle measuring 140 is equal to the sum of the two remote interior angles.
(X+2) + (2x) = 140. Combine like terms.
2 + 3x = 140. Subtract 2 from both sides.
3x = 138. Divide both sides by 3.
X = 46
Angle b = 2x. Substitute 46 in for x.
Angle b = 2(46)

Which of these expressions is equivalent to log (92)? O A. log (2) • log (9) O B. log (2) – log (9) OC. log (2) + log (9) OD. 2 • log (9)
Correct question is;
Which of these expressions is equivalent to log (9^2)?
Answer:
D: 2•log 9
Step-by-step explanation:
From log rules, we know that;
log(a^n) = n•log(a)
Applying that rule to this question, we can simplify log (9^2) as;
log (9^2) = 2•log 9
Looking at the options, the correct one is Option D
Work out the value of x
2x + 13
x-4
x+7
(Look at the photo attached)
Answer:
x = 41
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
2x + 13 + x - 4 + x + 7 = 180, that is
4x + 16 = 180 ( subtract 16 from both sides )
4x = 164 ( divide both sides by 4 )
x = 41
Answer:
x=41
Step-by-step explanation:
we know that all the angles need to add up to 180
The angle on top is almost a right angle(90) but is not exactly
playing with the numbers will help
95-13=82/2=41
lets continue with this and see if it works out
41+7=48
41-4=37
48+95+37=180
